 ## Executive summary
 
-On kernels with an older Landlock ABI, the launcher prints a benign partial-enforcement notice before executing every child. The harness treated that shared `landlock-run:` prefix plus any nonzero child exit as launcher failure, so ordinary outcomes such as ripgrep's exit 1 for no matches surfaced as `SANDBOX_UNAVAILABLE`; the then-bash-backed filesystem search also hid that structured error behind `SEARCH_FAILED`. Broad signature rules and missing partial-ABI composition coverage let the defect through. Runner classification now requires status-gated fatal evidence after exact informational exclusions, and an assembled keyless scenario pins the surviving bash path. Filesystem search has since moved to packaged ripgrep through the subprocess seam and no longer crosses sandboxed bash.

 - The sandbox provider reduced that contract to `runnerFailureSignatures: ['landlock-run: ']`; the bash consumer combined the prefix with any nonzero exit and reported stderr's first line.
 - Unit tests covered clean success, denial diagnostics, and fatal runner prefixes. Real-runner tests self-skipped without a usable kernel and did not force partial enforcement followed by a nonzero child.
 - A minimal POSIX wrapper that prints the notice and `exec`s its payload reproduced the failure with `false` and ripgrep no-match.
-- Structured rules plus shared foreground/background classification and assembled replay coverage closed the surviving sandbox attribution gap. Before this fix was reconciled with current `master`, filesystem search moved to packaged ripgrep through `ctx.subprocess`; the obsolete bash-adapter patch and tests were dropped instead of reintroducing the old architecture.

 - [`dsh-bash-sandbox`](../../packages/bash/bash-sandbox/) directly spawns the provider argv, so a pre-start rejection uses the spawn-error channel instead of localized shell diagnostics.

 ## 摘要
 
-在 Landlock ABI 较旧的内核上，launcher 会在执行每个子进程前打印一条无害的部分强制执行通知。harness 把共享的 `landlock-run:` 前缀与任意非零子进程退出组合起来，判定为 launcher 失败，因此 ripgrep 在没有匹配项时以 1 退出等普通结果会呈现为 `SANDBOX_UNAVAILABLE`；当时仍由 bash 支撑的文件系统搜索还会用 `SEARCH_FAILED` 遮蔽这个结构化错误。过于宽泛的签名规则，以及缺少较旧 ABI 下部分强制执行的组合测试覆盖，让该缺陷得以流入。runner 分类现在会先精确排除信息性行，再要求由退出状态门控的致命证据，并由一个组装后的无密钥场景固定仍然存在的 bash 路径。文件系统搜索后来已改为通过 subprocess seam 运行打包的 ripgrep，不再经过沙箱化 bash。
